Ash Determination Muffle Furnace is a high-performance, integrated, energy-saving and intelligent new product, mainly used for determining the content of plastic glass fiber and other components. It is an ideal equipment for scientific research departments of plastic processing and manufacturing enterprises, as well as universities. The device can intelligently control time and temperature in segments. It complies with ISO 3451-1:1997 and GB/T 9345.1-2008 Plastics — Determination of ash — Part 1: General methods.
I. Main Product Features of Ash Determination Muffle Furnace
1. The box-type resistance furnace for ash and glass fiber content determination adopts advanced technology. The furnace shell is made of high-quality steel plate through edge folding, welding and drawing processes. The control box and furnace body are integrated, with a beautiful appearance, avoiding the tedious installation work for customers.
2. The inner furnace lining is a rectangular integral lining made of high-alumina and silicon carbide refractory materials. The spiral heating elements wound from iron-nickel-chromium aluminum alloy wires are installed in the wire slots on the upper, lower, left and right sides of the inner furnace lining.
3. It adopts heating from the upper, lower, left and right sides. The interior of the furnace is a sealed structure, and the insulation layer is built with refractory fiber aluminum silicate cotton and diatomite products between the inner furnace and the furnace shell.
4. The overall design is reasonable, with a long service life. The furnace door is on the left side, and it is equipped with a chimney exhaust device, making operation convenient.
5. It has a beautiful appearance, fine workmanship, is sturdy and durable, and not easy to deform.
6. Temperature control: The box-type resistance furnace for ash and glass fiber content determination is equipped with an over-temperature alarm device, adopts an overall design and humanized menu design, and uses industrial PID self-tuning control technology. It has a dual-screen high-brightness wide-view digital display, with clear and intuitive readings. The microcomputer intelligent control solves problems such as temperature overshoot, and has excellent temperature control effect. After setting the temperature, the instrument automatically controls the heating output, ensuring precise and stable temperature control. It will alarm when over-temperature and automatically cut off the heating output. It has the functions of timing on startup or starting timing after reaching the set temperature for constant temperature.
